Deficient or locked-out?

This is a grow in Sunshiine #4, 5 and 7 gallon pots, 5'x7'x8' area, 2200w vented shaders in an otherwise sealed room. AN Sensi 2 + program as per AN nute calculator for veg, flipped to 12/12 and began AN connoisseur 2+ program Light Feeding on AN nute calc. Temps don't exceed 78F in veg (no CO2) and run about 84-86F in bloom with CO2 matching PPM in food. Humidity @ 50%, RO water always Ph'd between 6.2 and 6.4. The weekly reg is 1 feed, then 1 water with Sensi CalMg (and GE Seaweed Extract every other week), and one water with straight PH'd RO water. Each watering is just until runoff....hand watered.

Zero issues through veg. Growing Querkle, Sweet Pink GF, and Cotton Candy. About 10 days into 12/12 I noticed a few spots, and now on day 12 its getting worse. It only seems to be affecting the large fan leaves, and it hit the Querkle more than the others.....the pic is the MOST affected leaf. Plants are otherwise looking AMAZING.

TIA! Aloha

I get that sometimes, it's calcium deficiency ... start using your Cal-Mag additive with every gallon of water, every watering (try 10ml/gal), see if the new leaves don't look better :jointsmile:

Thanks.....thats what Roy at AN said too, just by an over-the-phone description! I guess I haven't been using my CalMg in the best way considering I'm using RO water. I also may have had some issues using Barricade, which needs time to completely dissolve and stablize in the water. Any other input is appreciated

Aloha

Use your CalMag all the time. Add it to your res first, then add the other ferts, then adjust the pH. Do a complete res change if you think the barricade may be interfering- Lose any supplements you are using until you straighten the problem out and it stops spreading.

my ex-wife said I was mentally 'deficient', so I was 'locked out' :jointsmile: ... ohh, sorry, wrong thread, misunderstanding ... that title confused me :stoned:

Tsk tsk, SHE musta been deficient to be locking out a fella as charming and handsome as yourself! What was she THINKING!? Maybe she just needed calcium... Ca deficiencies in middle-aged women are easily fixed with a regular application of chocolate ice cream. Frozen yoghurt is NOT a better approach, even though it might appear the more logical solution- you WILL be asked 'so, you think I'm fat?'- so just bring a nice pint of Ben n Jerry's. The regular stuff. Trust me.

Thanks Stinky.....those were the exact intructions I was given by AN! Mix CalMg to 50ppm then add ferts and Ph. I'm dropping the Barricade for now.....for that one he said to let it sit overnight in the res before mixing ferts....otherwise it can creep up as it (slowly) dissolves into the water. BTW, the Querkle is looking superb...

unfortunately, she also knows how to handle us 'dirty old men' :(

Haha! That's right, look out mister!
I know that when in the company of dirty old men, you should keep a disassembled piece of equipment between you and them at all times, and if he makes a move, say, "Oh hang on, can you grab my METRIC socket wrench set?" and then make a dash for the door, lol!

Well, it seems to be spreading fast on the Querkle...but is hardly affecting the Cotton Candy, and almost non-existent on the SPGF. I gave them a good dose of Sensi CalMg Bloom, so hopefully we'll see it slow down/dissappear. Thanks again

Aloha

Different strains feed at different rates- you might have to start mixing up their feed separately if it becomes apparent that they can't all handle the same fert mix.

Stinky,

Do you think the Querkle was using it up faster, and needs to
be fed more? Hence, the def started first on them? I went with the light feed program since this is my first run with Connoisseur....but perhaphs Querkle likes more!?!

I foliar fed with Revive while the pots dried out, then fed as normal (also adding SensiCal to every liter of water)....and things look like they are picking up. Thanks again

Aloha
